> There is a problem to create a web service with the xmlbeans mode. I tried the following scenario in Axis2.1.1.1 and Axis2.1.2 but I have the same error each time.
> 1) I generate the server part with the command:
>    $AXIS2_HOME/bin/wsdl2java.sh -uri myService.wsdl -p my.package -o /tmp/my/dir/server -d xmlbeans -s -wv 1.1 -ss -sd
> 2) I compile and deploy the server in Tomcat
> 3) I generate the client part with the command:
>    $AXIS2_HOME/bin/wsdl2java.sh -uri myService.wsdl -p my.package -o /tmp/my/dir/client -d xmlbeans -s
> 4) I compile and start the client and I got the following error as soon as the client tries to call any method of the web service:

> After analysis, I found a workaround to my problem. By analysing the web service example of the Axis2 tutorial, I noticed that the WSDL included this definition:
> >>>
> elementFormDefault="qualified"
> >>>
> Since I didn't have it in my web service, I added this definition in my XSD and the NullPointerException doesn't not occur anymore ! 
> If this definition is required in the XSD schema, Axis2 documentation should mention it.
> Thanks in advance.
> PS: This problem has been submitted to the User mailing list:
